[Tutorial] Battery saving techniques

So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !

I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

Hi.
I think that autobrigthness it's very hard in all phones. It would be an app Download the brightness.
Bye.

In my testing having wifi connected(like ay home and not going saves more battery, this been texted in several android devices including gs3,note 2 and iOS like 4S and iPads, just giving some info

Why dont you buy an old nokia since you almost get rid of all the cool stuff this phone offers? Brightness to lowest level...that cracked me up lol

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.

Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.

That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it

Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.

I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.

So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.

Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand

What about those external battery things? Does anyone know where I can find some decent ones online?

Google services is killing my battery on HTC one

According to gsam Google service Is the culprit if ny high awake times (see screenshot below). But how can I reduce this problem without defeating the purpose of having a smartphone,and according to the battery graph u don't see Google services listed at all.

/facepalm
A 21-minute wakelock out of a 12 hour recording session. The sky must be falling.
Unless you shut down any Google app using Google Play Services, no, there's nothing to do. The only reason it comes up as a larger power use is because it's essentially aggregating the power previously used by six or seven different apps. You seriously need to get some perspective on what constitutes "bad" battery life because you just keep posting "my battery suxorz" threads with less and less justification each time.

Hmm. I get pretty crappy battery life, but that battery life doesn't look too good. How much screen time? Your kernel should use about 25% of your battery. If you're on stock, that is.
Try clearing cache for GP services. Try using the phone for a day. See if that works. If not, then clear data.

Here is my current stats also I'm completely stock (no root) and my herbal US currently 23%,how much higher(percentage wise) can it get before it will start causing orovkens?

For stock non rooted,that seems about right. That's what I get. Around 13 hours a day with 3 how screen time.
Actually, you are getting much better battery life than I do.
What are your settings? WiFi? LTE? Battery saving apps? Facebook? I can't for the life if me get decent battery life. As I said, the kernel uses up 25% of my battery.
EDIT: Also, I looked at my stats, and it seems that Google services wakes my device a lot too. So yeah, your stats are normal. :good:

Is this normal for me? I left my phone overnight and it goes to deep sleep with barely no screen time but there's major drain. What is the difference between screen on time and awake? Is it some background services running? I checked the wakelocks and nothing seems wrong.
Edit: Looks like something is keeping the kernel awake. Does anyone know what is msm_hsic_host?

I only use the power saver with cpu,and data connection enabled,auto sync disabled,I'm on wifi when at home,and 3g/lte enabled when im away from home all the time,auto-sync disabled (no need for it). NFC and all location services are on all the time (google's location service along with GPS),brightness set from 0%-20% (depending on lighting conditions). I also use the facebook app with syncing disabled.If you have any other questions or if I missed something feel free to ask.

it ranges from 20%-25%,once it got up to 28% but I was doing some heavy gaming,but after that it went down to 23% according to gsam's app sucker on the % power used screen. I'm rarely in a low signal area, but when I am i'm not in that area for long enough time for it to really impact my battery.

I'm going to have to agree here. I think people are expecting way to much out of these machines. Especially if your gaming and browsing a lot. Assuming your not crippling your smartphone functions by disabling data and such,This phone is only rated for about 3 or 4 hours screen on time max, especially while gaming. 12 hours of battery is perfectly fine. Especially for the use case of the OP.

12 Ways to Save Battery without Root and break 7hrs SoT

I put together a list of things that helped me get 7 hours SoT on a charge (Wifi). Edit: 6.75hrs SoT. Edit2: 7.75hrs SoT No root access or modifications needed for these.
This is my first Android device and I wanted to share some of the things I've learned mostly reading these forums. It also annoys me to read users complain about their battery life but are unwilling to do anything about it. I hope this will help people to realize the full potential of their phone.
Llama, Tasker, etc: Automate everything you can to save battery. It can be more efficient to run a line of code then to tap the screen.
Force stop all the programs you don't really need running in the background in Settings > Apps > Running. Basically act like your own Greenify. Or use Greenify.
Wakelocks: Track the "Awake Time" of suspicious applications and services and either reboot or force stop them if necessary.
Disable Google applications you don't need. Myself I disabled Chrome, Gmail and News & Weather.
Disable: touch and typing vibration. I have type sounds On and touch sounds Off because those really add up on speaker.
Disable: NFC, Bluetooth, Wireless printing etc. Automate to run only when needed for no lost functionality.
Wifi: Automate to turn on only for Wifi zones of your choice. No lost functionality. Wifi always scanning: Off.
Notifications: Apps and games can send you unnecessary notifications. Disable them. Enable only what you need.
Hotword detection: off. This specifically drains SoT and saves only a single screen tap.
Widgets: These drain battery without ever showing up individually on the stats page. Silent killers.
Lux: Another silent killer even when set "On Wake only" and "Slow". Just by disabling Lux lite and a once-daily updated Feedly widget I noticed significant SoT gains. Using Llama to automate brightness is more efficient.
Speaker vs Headphones: The speaker seems to use more battery.
Two apps that can help you monitor your battery and phone with no root requirement:
Play Store Link.
Current Widget - Set to update manually on your home screen for minimal power draw. Check your charge and discharge rates along with battery temperature.
Play Store Link.
S Tools+ - This just popped up in the XDA apps section the other day. Detailed information on CPU states, Deep Sleep time and ALL your sensors, nicely graphed and very polished including transparent nav bar. Other than real time graphing of sensors this shouldn't be much of a drain.

Speaker vs headphones....what?? Care to explain how? I'm saying the difference is negligible.
Sent from my Nexus 5 using xda app-developers app

Yeah, you really don't need to do all that to save battery. Just don't turn on data until you need it and you'll get a week of standby on a single charge with this phone, and a full day of usage (or more depending on how much you use it).

I seem to drain more battery listening to music with speakers over headphones but its hard to tell and probably negligible, as you say.

Not sure if serious or not. That functionality is enabled on the phone by default and you'll see many people struggling to get over 3 hours SoT like that.
There are even reviews which seem to think topping 3 hours SoT is some kind of miracle. Most will answer that by saying: "you need root and flash x ROM with y kernel".

Gotta agree. The vast majority of users charge overnight and with my own setup - currently on stock rom and stock kernel (though I'm currently bouncing between that and Franco to see which I prefer) with pretty much everything always on (NFC, WiFi, data, location access, though I disable notifications from the likes of Facebook, Twitter, etc. just because I'm not that invested in social networks that I'd want constant updates) I can get 3+ hours SOT - which I'd assume is more than enough for most people. Greenify is to thank for most of my battery savings.
But don't get me wrong - for those who do need more SOT than that, the OP is fantastic advice, and I'll be coming back to this thread when I'm on holiday etc. and won't be able to charge every night.

great tips
kuddos to the OP

don't mind the haters. they're just mad that they only get 3 hours of screen on time and 10% battery drain per hour when deep sleeping
they would rather complain than take control of their device and if you dont use your own phone exactly like they use their phone, then they call foul and tell you that your results don't matter. they say the same thing to people that use their device like an ipod touch(by putting it in airplane mode).

I think it's just really hard to get good auto brightness on this phone right now due to the sensor. Using Lux Lite didn't help me very much since I was bouncing between very low and extremely high brightness but I imagine the full version could be more useful.
Llama is an extremely light weight application and uses only 6MB of RAM, the lowest of any service I've seen. I think it could add to Android System drain but using Cell Tower locations and properly set up conditions I don't think it will by much.
Thanks for the supportive comments. I really just want to help and have no hidden agenda here. We've known for months now that the N5 can get 8.9 hours SoT web browsing on WiFi and 6.9 hours web browsing on LTE. Of course Anandtech used perfect, non-root conditions with airplane mode On, Gnow off and zero apps or widgets; something that even I am unwilling to put up with. We can still strive to get as close to those numbers as possible.

Generally speaking SOT depends on what you are doing.
I've been down this road and can get SOT times on any phone pushing 5 hours.
To say no loss of functionality is wrong. You state to kill half the apps that I use so that is a LOF to me.
The secret, well not really, is the brightness and network reception.
Turning down the brightness and getting max signal/bandwidth will affect the battery more than turning off apps. Remember the rule of thumb the longer the phone has to stay on for a wakelock the more the battery drains and that is SOT and sleep. What I mean is you'll drain your battery faster connected to a dialup internet connection than fiber at 1gig.... It's all about bandwidth and high signal strength and screen brightness.
Not hating just saying that no one person can say this will give you X number of hours of SOT when everyone's signal/bandwidth environment is different.

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL

Greeny can also help but may need root

I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.

I loose only 2% for 7h of standby last night.

We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?

I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why

Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.

Delete it pls.

Horrible Note 4 Battery Life. Android System Draining Way Too Much Battery.

So I have a T-Mobile Samsung Galaxy Note 4, I got it back in October so yes I have "broken in" the battery. I have checked out several other posts and tried pretty much everything. I've turned off bluetooth, NFC, any and pretty much all useless Samsung features (smart stay, turn over to mute, multi-window), I've got a black wallpaper on for both my home and lock screens, I have greenify AND DU Battery Saver, I ONLY ever use data as I have unlimited data and my building has a shared wifi network which I don't trust, I have tweaked Sync in the settings menu to only sync crucial info from all my accounts (google, facebook, email, whatsapp, etc.). So far the BIGGEST battery drainer is Android System. It is always number one. I've had days where I've decided to push the screen-on time to its limits and have used it nonstop. Screen consumption only ever gets close even if I use my phone nonstop Android System is the biggest offender. I've tried keeping power saving mode on 24/7 but that has not seemed to help at all. I've disabled S Health, S Voice, and several other apps I never use like Google Play Newsstand. I am at the end of my rope I despise this phone for its claim to great battery life but its absolute GARBAGE real world performance. I consider myself lucky to get over 3.5 hours SOT. At this rate I might as well have an iPhone 5. I have no idea what to do.
Here's a list summarizing the things I've done to improve battery life:
Bluetooth off
NFC off
Multi-Window off
All email sync set to Manual
Sync for every account adjusted to isync only crucial info
Pitch Black Wallpaper
Power Saving Mode (Not Ultra Power Saving) switched on about 90% of the time
Using Greenify on all Power-Hungry apps
Closing most apps upon finishing using them
Using DU Battery Saver in order to monitor battery activity
Never use Wifi
No Multi-Window
No Touch Sensitivity
No Side Key Panel
Wifi Calling feature disabled (I never use wifi anyway)
No Download Booster
No Smart Stay
Animations switched off via the Developer Options
Tried using another battery (similar if not identical results)
I'm still getting at the very best if I'm somehow on a miraculous streak of good luck that day: 4 hours of Screen-On Time. It is ALWAYS Android System usually followed by Android OS and then an app or two before Screen (because my SOT is so pathetically terrible)
I love this phone, the display is beautiful, the camera is fantastic, it runs seamlessly (on Nova Launcher that is), BUT I despise the battery life. It has made me resent this phone and I'm seriously considering switching to the iPhone 6 Plus as that has comparable battery life and with it running iOS I doubt the OS would destroy my battery the way Android has been lately. What do you guys do to get such good battery life from this phone? I've tried everything I know!! Please can you help guys?
I'm also attaching screenshots from one of the BETTER days.

I would consider rooting and installing a custom rom, poprock I would recommend for keeping touchwiz.
I don't know.. maybe your battery is the problem.. When I was on stock I had the same issue, but i varied in a weird way. With poprock, battery life has been amazing.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

Are you still on KK or LP?

the battery distribution and the SOT is what I usually get too.. but the usage of 7 hours is too little. I always get over a day..

I'd already seen your thread. It wasn't too helpful for me unfortunately because I'm not rooted. Half the terms you guys were using "Odin'd, pit file, etc." I don't understand at all. I'm running Nova Launcher on this phone. Just typing this comment my battery has dipped from 78% to 74% this is ****ing ridiculous I'm sick of this **** phone I might just switch to iPhone. I'm done with battery raping Android.

I'm in the process of fixing this. I think I may have figured something out. I have been slowly working through freezing applications to figure out what is causing the battery drain. I've made some progress. I really think it is an issue with lollipop system apps.
I am now having a slight dragon from cell standby, but the Android System drain is getting capped. Been in this single charge for 17 hrs and Android system is only 7%
Once I get a bit more firm information I will post my findings.

Some suggestions: check out your Google settings first. Disable Google Now and uncheck their location monitoring settings. Also freeze Facebook (use the website instead). Finally ou can disable sync altogether for a while in case other apps are hammering away through it. Test your battery under each of those conditions. Good luck, be patient, take your time. If your battery is good eventually you'll get to the bottom of it. Use Better Battery Stats to monitor. Most people get fantastic battery life. I rarely use 40% in a day. Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Thanks I'll try some of that but my problem is that I shouldn't have to do all of this crap! God it seems like we HAVE to revert these superphones back to pre 2000 dumb phones in order to get any kind of a decent battery performance from them. Samsung just haaaaaad to make the screen 2K. If they'd kept 1080p it might've been better! I might as well just switch to the iPhone 6 plus if I want ZERO functionality from my big screen phone. God I hate this Note 4 and I'm so jealous of people who don't do anything like this and still get 5-7 hours of SOT with their Note 4's. I'm beginning to think they're full of it honestly.

Nope. Either replace the phone or wipe and start over since u not rooted very little help.

If you're not rooted do this:

If you are scared of root just stay stock rooted. Not a slight at Bacardi. He answers the questions better than us.

I am have the same issue with battery drain from Android System. I have see that issues is there when WiFi is enable the battery drains faster. When WiFi is off and using mobile data it drains normal.

I will be watching this carefully. I have the same issue. Always Android system and Android OS in the top 3 battery drainer. Only, issue I have is I have to use WiFi at home. T-mobile service drops to Edge about a half mile before reaching my neighborhood.

If you click on the Android Systems within the Battery usuage section. It will give you more detail, and show you what services, or packages are using it. The. You can take it from there.
